Description
Schmelzofen (Siemens-Martinofen) mit Kohlenstaubfeuerung. Schmelzöfen (Siemens-btartinöfen) mit Kohlenstaubfeuerung und mit gleichbleibender Flammenrichtung, wobei die Abgase mit Hilfe eifies Rekuperators zur Vorwärmung der Sekundärluft verwendet werden, sind bekannt.Melting furnace (Siemens Martin furnace) with pulverized coal combustion. Melting furnaces (Siemens btartin furnaces) with pulverized coal combustion and with constant flame direction, The exhaust gases are used to preheat the secondary air with the aid of a recuperator are known.
Derartige Men .eignen sich jedoch nur für kleinere Leistungen von etwa 3 his 5 Tonnen, während hei größeren Ofen für entsprechend größere Leistungen die Wärmewirkung nicht ausreicht.Such men, however, are only suitable for smaller performances of about 3 to 5 tons, while in larger ovens for correspondingly larger outputs the heating effect is not sufficient.
Die 1?rfindung besteht nun darin, daß zwei Staubverbrennungskammcrn am einen Ende des Herdes einander gegenüberliegend angeordnet und der Abstich des Schmeizgutes am gleichen Ende des Ofens zwischen die beiden Staubverbrennungskamm-ern, mithin an die heißeste Stelle des Ofens, verlegt wird. Die Aufgabe des Schmelzgutes dagegen, die bei den bekannten Ofen auf der Seite liegt, erfolgt in diesem Falle am anderen Ende des Herdes, dein Abstich gegenüber, wo die niedrigste Temperatur erreicht und die Abgase nach beiden Seiten in die Rekuperatoren zur Vorwärmung der Sekundärluft abgeführt werden.The invention consists in the fact that two dust combustion chambers arranged opposite one another at one end of the stove and the tapping of the Melted material at the same end of the furnace between the two dust combustion chambers, is moved to the hottest part of the stove. The task of the melt material on the other hand, which is on the side in the known oven, takes place in this case at the other end of the stove, opposite your rack, where the lowest temperature reached and the exhaust gases to both sides in the recuperators to preheat the Secondary air can be discharged.
Der Ofen ist in der Zeichnung in Abb. n bis 3 in verschiedenen Schnitten dargestellt. a. ist der Schmelzraum mit dein Schmelzherd, >>, und b, sind die beiden einander gegenüberliegenden Staubverbretinungskammern. Der Abzug der Rückstände dieser VerbreinungskaniMern gaschieht seitwärts bei in, und in,. Die Kammfern selbst - sind zweckmäßig senkrecht ausgebildet, und das Staubluftgemisch wird senkrecht von oben durch die Brenner d, und d._ eingeführt. Der Staub erärnit sich in diesen Kammern derart, daß Staub und Achsenteilte nicht in den Schmelzraum gelangen, sondern sich vollständig am Boden der Kammer niederschlagen. Der Abstich i des Schmelzherdes liegt in der -.Mittelachse des Ofens mitten zwischen den beiden Staubverbrennungskammern an der Stelle, wo die Verbrennungsgase aus den beiden Kammern zusammentreffen. Die Aufgabe des Schmelzgutes erfolgt dagegen am gegenüberliegeid'en Ende des Herdes durch die Öffnung Ir. DieVerbrennungsgase verlassen den Schinelzrauin am hinteren Ende nach beiden Seiten, so daß zwischen ihnen die Aufgabestelle liegt. Die Abgase werden zu einen abseits angeordneten Rekuperator g geführt, aus dem die vorgewärmte Verbrennungsluft durch eine Zuleitung f in die Heißluftkanälee, unde_ strömt.The furnace is shown in the drawing in Fig. N to 3 in different sections. a. is the melting room with your melting hearth, >>, and b, are the two opposing dust incineration chambers. The withdrawal of the residues of these compounds is carried out sideways at in, and in ,. The chambers themselves are expediently designed vertically, and the dust air mixture is introduced vertically from above through the burners d and d. The dust in these chambers is such that dust and parts of the axis do not get into the melting chamber, but are completely deposited on the bottom of the chamber. The tapping i of the melting hearth lies in the central axis of the furnace in the middle between the two dust combustion chambers at the point where the combustion gases from the two chambers meet. In contrast, the melting material is fed in at the opposite end of the hearth through the opening Ir. The combustion gases leave the Schinelzrauin at the rear end on both sides, so that the feed point lies between them. The exhaust gases are led to a recuperator g, which is arranged on the side, from which the preheated combustion air flows through a supply line f into the hot air ducts, unde_.
